WARE-SUPPORT ron KILNS. i

Application led May 20,

Be it known that I, PAUL citizen of the United States, and residentof New Castle, in the county of Lawrence and VState of Pennsylvania, have invented certain new and useful Improvements in Vare- Supports for Kilns, ,of which the following is a specification. y

The general object of my presentinvention is to provide improved means for supporting wares in kilns andpmy 'invention was'primarily devisedto provide improved supports for wares such as lass pots moved into and out of annealing lilns or furnaces on cars.

The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, however, and the' advantages possessed by it reference should be had to the accompanying drawings and descriptive matter in which I have illustrated and described preferred embodiments of my invention.

On the drawings Figure l'is a side elevation of an annealing kiln car having a glass potsupported thereon by my improved supporting means. n y

Fig. '2 is a plan view of the apparatus shown in Fig. l..

Fig. 3 is a partial section on the line 33 of Fig. l, and y Fig. 4 is .a diagrammatic plan illustrating a modification of the apparatus shown in Figs. l and 2.

In the vdrawings A represents a car of the type used for transporting goods through the so-called continuous tunnel kilnsy AThis car as is usual is formed with a top portion of refractory material. Inthe car top A1 proper are formed a plurality of recessed seats B, and in each seat B rests a supporting body having a spherical seat engaging portion and a flattened seat C2 on which theY goods rest. As shown in Figs. 1 and 2 there 'are three of the goods supports C, each resting in a corresponding recess B. Resting on the fiat sides C2 of the supports C is the object D to be treated in the furnace. As shown-the object D is a pot for holding molten glass after the pot is gradually brought up 'to a sufficiently high temperature'. F or this use the supporting bodies C Specification of Letters Patent.

may well be formed of fire clay and may be in the nei hborhood of fifteeninches in diameter. s .shown the bodies C are each formed with a diametral hole C1 through which a bar may be passed by means of which the body may be-lifted. Preferably, as shown, the seats are spherical but have a radius of curvature slightly greater than that of the seat engaging portions of the supports C.

In handling ware likeI a pot D it is desirable to employ pier-like supports holding the pot above the top of the car body proper.

Thisprotects the pot from too rapid heating at its bottom when, as will usually be the case in theparticular use specified, the pot is placed cold upon a car still quit-e hot from a previous passage through the,r kiln.

The sphericalsupports C shown form de.

sirable means for thus protecting a cold pot from the heat of the car body, and it is obviously a simpleand easy matter to replace the supports C on a car which has just passed through the kiln by-other supports C which are cool. When, as will ordinarily be the case, the pot which may weigh several hundred pounds is lowered into place on the car by an overhead crane or the 1ike,it is [of course difficult to avoid some shock tending to displace the pier-like supports when the weight of the pot is transferred from the overhead supporting mechanism to the supports. With the construction described, however, this does no harm since the supports C may roll or slidev in their seats B suiiiciently to enable them to'take the load of the pot properly. The' use of these supports as shown gives a three point bearingfor the pot which insures the proper distribution of load on the different supports C. The flattened seats C2 may well be made of ample area to avoid crushing strains on the supports or pot.

Where different sized pots are to be handled at different times on the same car, the

latter may be formed with a plurality of sets of seats forsupports C. Thus, as indicated in Fig. 4, there may be three seats -B1. provided on the car A10 for the supports to take arelatively large pot sayv of the same general horizontal outline as the car and another set of three seats B2 may `be provided in which the supports are placed when a smaller sized pot, as for instance one having the outline indicated by the dotted line (l, is to be* mounted on the car.

'While in accordance with the provisions of the statutes 'I have illustrated and described the bestform of my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form of theapparatus disclosed withe out departing from the spirit of my invention as set forth in the/appended claims.

' Having now described myinventiomwhat I claim as new and desire to vsecure byv Letters Patent7 is:l y

2. As. a new article of manufacture a'.
